"It's not that difficult to estimate what the costs will be if you have some idea of the numbers of troops."
On Friday, the Congressional Budget Office released a report estimating the total cost to occupy Iraq from 2004 through 2013 at between $85 billion and $200 billion, depending on how many American soldiers are needed and how soon they can leave Iraq.
Rumsfeld defended the Pentagon's pre-war vagueness at an October news conference, saying: "We were criticized for not giving answers because we didn't know the answer."
Former White House economic adviser Larry Lindsey also came under fire last year when he estimated a war with Iraq could cost between $100 billion and $200 billion. Mitch Daniels, then Bush's budget chief, discounted the estimate as "very, very high," and the issue was cited as one of the reasons why Lindsey resigned in December.
